Patented is a coating film end tape structure with a core and end tape with opposite first and second ends. A first single-sided adhesive tape is adhered to the core, overlapping the end tape at a location adjacent the first end of the end tape and connecting the end tape to the core. The first end of the end tape is located between the first single-sided adhesive tape and the core so that an adhesive layer on the single-sided adhesive tape adheres to an outside face of the end tape when the end tape is wound on the core. The overlapping parts of the end tape and the first adhesive tape constitute a first adhered section with a thickness equal to the sum of the thicknesses of the adhesive tape and the end tape. A coating film tape overlaps the end tape at a location adjacent the second end of the end tape; and a second single-sided adhesive tape overlapping, and adhered to, one of the end tape and the coating film tape at the location of the overlapping parts of the coating film tape and the end tape. The overlapping parts of the end tape, the coating film tape and the second single-sided adhesive tape form a second adhered section with a thickness equal to the sum of the thicknesses of the end tape, the coating film tape and the second adhesive tape. The second adhesive tape is also adhered to the other of the coating film tape and the end tape at a location adjacent the overlapping parts of the coating film tape and the end tape. The overlapping parts of the second adhesive tape and the other of the coating film tape and the end tape constitute a third adhered section with a thickness equal to the sum of the thicknesses of the second adhesive tape and the other of the coating film tape and the end tape. An adhesive layer on the second single-sided adhesive tape adheres to inside faces of the coating film tape and the end tape when the coating film tape and end tape are wound on the core. The thickness of each of the adhesive tapes is not greater than 25 microns. The thickness of the first adhesive tape is from 30% to 70% of the thickness of the first adhered section. The thickness of the second adhesive tape is from 20% to 70% of the thickness of the second adhered section and at least 30% of the thickness of the third adhered section
